Can you add on a picture so that i can help you answer this question
Group 7
Explanation:
The unknown element belongs to the seventh group on the periodic table of elements.
Ionic bonds are usually formed between metals and nonmetals. They formed by the transfer of electrons from the less electronegative specie to the more electronegative one.
The metals usually lose electron because they are highly electropositive species.
- If we have a magnesium atom with two valence electrons.
- To form ionic bonds, it must transfer the two electrons to another atom.
- The other atom, a nonmetal must be ready to accommodate and receive the donated electrons.
- This ensure that its own octet is complete.
- Group 6 elements requires 2 electrons to have a complete octet.
- They can receive the two electrons
But we were told that there are two atoms of that element for each of the magnesium atom;
the atom must have a capacity of collecting one electron each to be stable.
Such atoms are found in Group 7 on the periodic table.

Answer:
(D) Neither I nor II
Explanation:
The reagent potassium hydrogen phthalate is found in pure form and it is not partially hydrated .
The pallet form of NaOH ( solid form ) absorbs carbon dioxide gas from the atmosphere but NaOH in solution form does not absorb carbon dioxide .
Hence option D ) is right choice .
